Elastomeric Conductors and Shields - Patent Application 20090314510 - 0 views

  • Systems and methods presented herein provide for elastic conductors. The elastic conductors may be configured with a primary that includes an elastic material and a conductive material. For example, the primary may have an elastic fiber, such as spandex, with a conductive material, such as a braided metal wire, wrapped thereabout. Alternatively, the primary may be configured from an elastic material with a conductive material, such as certain nanopartiuclates, embedded therein. The elastic conductors may be used in a variety of ways to form various types of cables. For example, the elastic conductors may be configured to form coaxial cables, USB cables, twisted pairs, etc. The elastic and flexible nature of the cables may make their uses advantageous in wiring environments that are subjected to strain or other harsh conditions. Moreover, the relatively light weight of the cables may make their uses more advantageous in transportation (e.g., aircraft, automobiles, etc.).

Outlook for aluminum production - CCA substitutiion - 0 views

  • It will also be boosted by substituting copper, a practice that is more prevalent in China due to cost sensitivity and the absence of legacy issues where copper is already installed in wiring and cables in the country. It is seeing substitution to copper clad aluminum (CCA) cable and aluminum magnet wire in China from conventional copper products.

Substitution analyst comment - Wire and cable - 0 views

  • We have also started to see signs of companies substituting other inputs where possible. With copper prices at or near all-time highs, manufacturers of cables and wires have started substituting aluminum in place of copper. Even the U.S. government is studying alternative metals to use in coin-making, and with good reason: The pure metal value of a nickel today is almost $0.07! In the textiles industry, some companies have tried to use more cellulose fiber and less cotton.

IDC Connectors Help Motor Manufacturers Migrate To Aluminium - 0 views

  • Fabrizio Longo, Tyco Electronics product manager, says: "Many medium- and high-volume manufacturers of FHP motors for appliance, heating ventilation and air-conditioning (HVAC) equipment are evaluating a switch from copper to aluminium magnet wire to reduce raw material costs. Copper contributes on average about 30 per cent to the overall production cost of a FHP electric motor. Switching from copper to aluminium conductors can also reduce transportation costs, as aluminium is about one-third of the weight of copper. Our interconnection system allows manufacturers to easily and cost-effectively bridge the transitions many are making from copper to aluminium magnet wires."

Alcan Cable introduces NUAL® WIDESTRIPE™ RW90 aluminium alloy building wire a... - 0 views

  • Consisting of NUAL® aluminium alloy conductors, NUAL® WIDESTRIPE™ RW90 cable weighs half as much as copper conductors of equal ampacity, making it lightweight for easy, safe lifting and handling during installation. Alcan Cable’s NUAL® WIDESTRIPE™ RW90 XLPE insulation also has a higher maximum short-circuit temperature rating than thermoplastic insulation. It does not contain harmful components such as lead and other heavy metals in accordance with RoHS, Directive 2002/95/EC, and is manufactured to minimise adverse environmental impacts.

The country can't face the technological future through copper wire - 0 views

  • A future-proof technology is optical fibre, which has the ability to provide hundreds of gigabits to the home - thousands of times faster than HFC - and will serve us well for the next 100 years. Let's face it - can copper outrun the speed of light?

Scoop: Science Minister salutes super NZ technology - 0 views

  • The New Zealand-made high temperature superconductor carries up to 10 times the current of copper wire of the same size, without energy loss. In a world-first, the New Zealand scientists have produced commercially viable superconductor wire and cable – reliable, robust and economical. It consists of strips of a new material thinner than paint and sheathed in metal.

The Great Copper Heist - BusinessWeek - 0 views

  • Since 2001 the price of copper has gone from less than $1 per pound to about $4 per pound on the Comex division of the New York Mercantile Exchange (CME). In response, looters and scavengers nationwide are stealing copper where they can. Within the last three years, copper thieves have disabled 130 cell tower sites across 17 jurisdictions in eastern Virginia and North Carolina. They stripped the wire from an airplane control tower in Ohio, endangering in-flight communications. They scuttled the irrigation system of Pinal County, Ariz., causing $10 million in damage and ruining a harvest. In Indianapolis, gutted refrigeration systems cost the state's largest food bank $400,000 in spoiled rations. In Jackson, Miss., thieves stole the copper from five storm sirens, which then failed to warn residents of an incoming tornado. In Kansas City, Mo., power outages due to stolen wire caused a credit union to freeze bank accounts, while a separate group allegedly used a backhoe to excavate 18,000 feet of backup power lines worth at least $500,000. In western Nevada, bandits on four-wheelers took out signal and control systems from Union Pacific (UNP) and Amtrak rail lines. In Minneapolis and Cincinnati, police say gangs use foreclosure lists like treasure maps, looting pipes from hundreds of homes, some of which exploded from gas leaks.

For Wind, Is Bigger Better? « Earth2Tech - 0 views

  • American Superconductor said this week that it will work with the Department of Energy’s National Renewable Energy Laboratory and its National Wind Technology Center to look at the economics of building a 10-MW turbine. The Devens, Mass.-based company said it can get a bigger power punch but still keep the size and weight under control by using its high temperature superconductor wire, which it claims is lighter and more efficient than the copper wire traditionally used in wind turbines.

Wireless Data Acquisition Benefits Broad Spectrum Of Applications - 0 views

  • Lord Kelvin, the 19th century mathematical physicist and engineer, is famously quoted as saying: "If you can not measure it, you can not improve it." He has been proved right, of course, but even he could not have predicted the advances in metrology, the science of measurement, with wireless data acquisition (DAQ) being one of the most rapidly evolving technologies today. Where a wired approach can present logistical and cost-related problems, such as when accessing remote locations or crossing roads, wireless DAQ offers an alternative. With a protocol such as Zigbee, for example, each measurement node can communicate wirelessly to other nodes and, via an Ethernet gateway, to a PC.

5 surprising uses for carbon nanotubes - 0 views

  • Pure metallic carbon nanotubes could be the key to overhauling the electrical power grid with more efficient transmission lines - but only if they could be made in huge quantities and uniformly. Through a refined version of a technique called “amplification,” researchers at Rice University plan to make long and highly conductive nanotube fibers they dubbed “armchair quantum wire”  that could be woven into more efficient electrical transmission lines. They eagerly plan to generate a large quantity of this material by the end of summer. Aaron Franklin, a researcher at IBM’s Watson Research Center says that the update Rice study probably doesn’t reveal “the golden ticket for achieving high volumes of metallic-only tubes,” reports MIT Technology Review. We’ll just have to wait and see. Learn more.
